To all whom it may concern:

Be it known that I, WILLIAM F, REGAN, a citizen of the United States,residing at the city of New York, borough of Brooklyn, county ofKings,and State of New York, have invented a certain new and useful Method ofMaking Paper Bottles of which the following is a specification.

This invention is a method of making containers from fibrous materials,such as shaped paper bottles, whereby an article with a closed bottomand a tapering neck' portion may be manufactured rapidly andeconomically.

According to the preferred mode of procedure in producing the container,a prepared bottom member is positioned in cooperative relation to aforming mandrel,- and the fibrous material required to. form the body ofthe container is fed-or supplied to said forming mandrel, whereupon themandrel and the prepared'bottom are rotated, as a result of which thepaper is wrapped or coiled upon the mandrel and around the bottom. Thenext step is to infold the material with respect to the bottom, and tounite the bottom and the cylindrical material at one end portion of thelatter, thus resultin in an embryo container consisting of a cyllndricalbody and a bottom closure united thereto. Such embryo container is now,preferably, transferred'to a forming mandrel, the latter. cooperatingwith suitable mechanism which imparts a taper to'an end portion of thecylindrical body so as to produce a desired taper thereon, The materialof the cylindrical body is crimped for producing the tapering neck onthe container, and for confining the crimped material in place so as toovercome any disarrangement of the crimps, particularly at the neck ofthe bottle, a band is applied exteriorly to the crimped material,preferably by winding or coiling a strip or web of material around thecrimps at the neck adjacent to the mouth or outlet of the bottle.

The container producedaccording to the specified procedure ischaracterized by several features of novelty as follows :-,First, thecrimps in the neck portion. extend lengthwise of the container, they aretaperthe body and the closure for one end of said ing so as to increasein depth from the of which is within the chamber of the neck or body,thus leaving the external surface of the container comparatively smoothand free from projections; second, the crimped mined relation so as toprejlgide any breaking down of the mouth p0 ion and which mouth portionpresents a smooth external surface adapted for the reception of asuitable cap or closure, and, third, 'the bottom andthe cylindrical bodyare permanently united in a way to protect and reinforce the bottom bythe material of the container and to secure a liquid tight jointbetweensaid bottom and the container. L

Other features and advantages of the invention will appear from thefollowing detailed description.

In the drawings, Figure 1 is a plan view, partly in section,illustrating the first step in the formation of the container whichconsists in positioning a closure in operative relation to an end faceofa forming mandrel. Figs. 2 and 3 are plan and side views illustratingthe second step in the formation of the container which consists inwrapping a length of paper around the forming man drel and the closurepositioned againstthe end face of said forming mandrel. Fig. 4 is asectional, plan view illustrating the third step which consists inuniting an end portion of the container body to a closure for .saidcontainer body; -Fig. 5 is a plan view,

and end l elevation, respectively, illustrating the fifth step whichconsists in winding a neck band aroundthe crimped neck portion of thecontainer body. Fig. 8 is a side elevation of a: complete containerembodying the invention. Fig. 9' is a plan view of the container shownin Fig. 8. Fig. 10 is a horizontal section on the line 1010 of Fig. 8.

In carrying the invention into practice, I

employ a rotatable forming mandrel A to which is fed the materialadapted to form 1 body, thus resulting in a container, the body andclosure of which are united so as to result in a unitary structure. Thefirst step consists in positioning the closure against I said closuredisk is substantially flush with the cylindrical surface of the formingman-- drel. The closure having been positioned with respect to themandrel as described, I

. next proceed to form thec-ontainer body,

for which purpose a length of paper C 1s supplied to the mandrel,whereupon said mandrel is rotated soas to wrap orcoil the paper 6 uponthe mandrel and the flange of the closure. The paper or other fibrous material may be supplied from a Web or in sheets, it being preferred'tofeed the sheets successively to the forming mandrel. The

' paper is coated with an adhesive substance along'one side margin, asat c, and one edge margin, as at c.

I This coating may be supplied to the-paper and dried thereon in'theoperation of preparing the paper for use the machine, or, if desired,the adhesive'coating at .0 '0 -may. be supplied in a wet condition andby suitable devices.

during the operation (if feeding the paper to the forming mandrel. When'prepared sheets of paper with dried adhesive coatings thereon areapplied it becomes necessary to molsten the adhesive coatings before orduring the operation of feeding the sheet to the forming mandrel, andwhen the paper is coiled upon the mandrel the convolutions of the paperwill adhere to each other, theinnermost layer of paper adhering to theflange b of the closure.

Having wrapped the paper C around the mandrel and the closure, asillustrated in Figs. 2 and 3, the next step is to infold a protrudingportion of the paper around the gummed margin 0 thereof into. contactwith the inner surface of the flange b of the closure, substantiall asshown in Fig. 4. This is per formed by suitable mechanism during therotation of the mandrel, said mechanism bemg in the form of a bendingroll having one or'more flanges operating on the material to press thegummed margin 0 into contact with the 1nner surface offlange 6, wherebythe paper composing the body of the container is united to the flange bof closure B both exteriorly and interiorly of said flange.

Subsequent to the operation of forming the material into a cylindricalbody and' uniting the end closure to said cylindrical body the embryocontainer is transferred from forming mandrel A to a crimping mandrel D,illustrated more particularly in Figs. 5 and 6 The embryo container istransferred by any suitable means from mandrel A to mandrel D soas toassume the Serial No. 801,820, filed even date herewith,

for the purpose of crimping the material,

thus resulting in a tapering neck at an end portion of the container. Asshown, the crimping mandrel D is tapering at one end, as at d, and isprovided with a series of longitudinal slots d. With this mandrelcooperates a series ofexteriorly positioned crimping fingers which actupon the cylindrical' end portion of the container body soas to forcethe material into the slots (Z,

container body. constituting the ribs 6 are positioned interiorly of thecontainer, and they extend from the cylindrical part of the containerbody to the neck portion thereof. The material is crimped so. asto'impart the desired itaper to the container, and this material at oneend thereof is formed arounda collar D of the crimping mandrel, so as toproduce a substantially cylindrical mouth portion at the end of thetapering bottle neck. Obviously, the crimped material will not retainits shape unless means are provided for binding the crimped materialfirmly in position, and to this end a neck band is applied exteriorly tothe crimped material. It is preferred to feed a length or strip ofnarrow paper E to the mouth portion of me container, and to wind thisstrip or length of material exteriorly upon the crimped material at saidmouth portion, thereby prothereby producing a series of ribs 6 on theThe folds of the material" ducing a neck band which is firmly unitedquent to the application of the neck band,

mandrel D is collapsed in order to withdraw it from contact with thecontainer, and the latter is ejected by suitable mechanism from themandrel while the latter is in a collapsed state.

The procedure herein described results in a container, illustrated moreparticularly in Figs. 8, 9 and 10 of the drawings, the bottom of saidcontainer being closed by the flanged disk B which is united firmly tothe material ,of the body so as to secure a liquidtight joint therewith.The container F consists of a cylindricalbody, the neck portion 7 ofwhich is tapered by crimping the material so as to produce the webs e,the latter being in the form of ribs positioned interiorly of thebottle. The webs or ribs e extend lengthwise of the tapering neckportion of the bottle and they increase in depth from the.

cylindrical part of the body'to the mouth portion of the bottle, thematerial of the crimps at one end thereof being pressed firmly upon thecollar -D of the forming mandrel so that these compressed portions ofthe crimped material constituting the mouth of the bottle will be unitedfirmly together by the neck band E, the latter being formed by windingthe length of paper E around the crimped material next to the mouth ofthe bottl It is evidefit that the bottle may be produced rapidly andeconomically, for the reason that the several operations are performedby automatic machinery.

Subsequent to the completion of the bottle or other container, it ismanipulated or treated to render it waterproof, such, for example, as bycoating the bottle either interiorly or exteriorly, or both, withparaffin or other agents.

Having thus fully described, the invention, what I claim as new, anddesire to secure by Letters Patent is 1. The method of making paperbottles which consists in positioning a flanged bottom member intocontact with a solid end face of a rotatable non-collapsible formingmandrel, feeding a web of paper to said mandrel, rotating the mandreland the bottom' member simultaneously to wind the paper web upon themandrel and the flange of the bottom member,'infolding the coiled webinteriorly of the flange on said bottom member removing the resultingembryo bottle from the forming mandrel, positioning sa d embryocontainer upon a collapsible 1 'CIlIIlP-fOIIIllIlg mandrel, producingcrimps which consists in winding a web of paper upon a rigidnon-collapsible forming mandrel and simultaneously attaching a bottomclosure to an end portion of the coiled Web so as to produce on saidforming mandrel an embryo bottle, then removing the embryo bottle fromsaid forming mandrel, then inserting a collapsible crimping mandrel intothe open end of the embryo paper bottle, then producing longitudinalcrimps in the coiled material, then compacting said crimped material atthe open end of the embryo bottle and winding exteriorly thereon anarrowband, and finally ejecting the completed bottle from said crimpingmaterial.

3. The method of producing shaped containers from fibrous material whichconsists in winding a web of paper upon a forming mandrel and at thesame time uniting an end closure to the resulting container body,removing the embryo container from the forming mandrel and positioningthe same upon a crimping mandrel, crimping the material for definitedistances lengthwise of the embryo container while present upon thecrimping mandrel so as to impart a taper to the neck portion of thecontainer, and binding the crimped material by applying tapering abinder externally to the mouth portion of mandrel and at the same timeuniting a closure to an end portion of the resulting container body,removing the embryo container from the forming mandrel and positioningthe same upon a crimping mandrel, crimping the material of the containerbody and imparting a taper to the neck portion thereof by folding saidmaterial on predetermined lines and lengthwise of said body so as toproduce ribs which increase in depth toward the mouth of the containerand are posi tioned inwardly with respect tosaid container, and applyinga binder externally to the crimped material at the mouth portion of thecontainer.
